Currently running renders on a custom built rendering computer (so sorry I don't have the specs list on hand), but my renders are taking 10+ hours, and this project needs to be done by Monday night...
Any tips as to how to make renders go faster would be so appreciated. Here's the model stats in case it's helpful at all. Thanks!!

Run the podium analyse tool.(little wrench looking button)
Then post the results of that process and some of the more seasoned members may be able to see what could be causing the "slow" (although that may not be slow depending on a lot of factors) render. - One big factor - What preset are you using? - Another factor - Is there a lot of model outside of what you see in your view? If there is, organize your layers so you can turn of stuff you can't see. Lights, lights, lights, ...Time goes up exponentially the more artificial lighting you add. __________________ pmo

The first thing to note is that you have lots of curved surfaces here, and I'm betting that the number of faces of all these curves is high.
For rendering, you need to manage the polygon count of your scenes if you want good render performance. When you create anything you need to consider what it is going to be used for. Are you going to render it, and if so, what sort of scene, at what sort of distance. Just like you need to learn how to best use your tools to create the best results with physical media (I'm old enough to remember all the tedious business of cleaning technical pens, and the subtleties of drawing on coated film and tracing paper) 3D modelling is no different, you need to manage your tools and workflow. For tubular metal furniture, I tend to use no more than 8-10 faces, with the geometry smoothed. Unless you see things up close, you most likely won't see any difference, but render time, especially with reflective and transparent surfaces can be significantly longer. Add lots of light sources and render time goes up a lot again! Those columns and mouldings in your scene look poly-heavy. To improve performance, reduce your number of light sources, recreate your geometry with fewer polygons, and rationalise your reflective surfaces. If you have applied reflectivity to those mouldings - don't. If you have modelled those things as components, it will be much easier to remodel them with fewer segments. Unfortunately, these are lessons that we tend to learn when struggling with deadlines! __________________
